Abstract
The utility model relates to a return mechanism of a numerical control self-centering center frame, which comprises a cross arm, side arms, a cam, a piston, an oil cylinder and a connecting board, wherein the cross arm is connected with the cam, and the side arms are respectively arranged at both sides of the cross arm; the oil cylinder drives the cam to move through the piston so as to drive the cross arm to move, and meanwhile, the side arms swing around the revolving shafts on the side arms so as to clamp or loosen a workpiece; a sliding chute is arranged on the connecting board, and the connecting board is respectively connected with the sides arms and the cam through the sliding chute; and the cam drives the side arms to swing through the connecting board so as to clamp or loosen the workpiece. The numerical control self-centering center frame has the advantages that the return swing motions of the side arms are realized by the connecting board instead of a spring, so the phenomenon of the asynchronous return swing motions, which is caused by the size of resistance force, can not occur so as to avoid the phenomenon of fatigue fracture.
Description
Technical field
The utility model relates to a kind of numerical control self-centering centre frame.
Background technology
As shown in Figure 1, existing centre frame, drive to adopt hydraulic pressure to realize by oil cylinder 6, clamp action be fixed together by piston 5 driving cam 4(and transverse arm be synchronized with the movement), cam 4 drives side arm 2 wraparound rotating shafts to the swing of clamping work pieces direction by driving transverse arm 1, realizes clamping work pieces.Machine at workpiece to be machined, when needing discharging, need centre frame to unclamp holding workpiece, this moment, hydraulic drive piston moved to unclamping the workpiece direction, drive cam 4, transverse arm 1 to moving away from workpiece axis of rotation direction, simultaneously by two side arms 2 of spring 3 pulling to unclamping the swing of workpiece direction, realize unclamping workpiece, for the material loading of the unloading of finished work and new unprocessed workpiece gets out of the way the space.In the practical application, the spring of finding to be used for side arm 2 backswing 3 causes side arm 2 backswing action not in place often because of the frequent fatigue fracture that stretches, and has directly influenced the loading, unloading workpiece, can't satisfy instructions for use in the automatic loading/unloading lathe.
The utility model content
For addressing the above problem, the utility model provides a kind of numerical control self-centering centre frame.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of numerical control self-centering centre frame backhaul mechanism, it comprises transverse arm, side arm, cam, piston and oil cylinder, described transverse arm is connected with cam, the both sides of transverse arm are respectively arranged with side arm, described oil cylinder is by the piston actuated camming movement, thereby drive the transverse arm motion, thereby side arm is swung clamping or is unclamped workpiece around the gyroaxis on the side arm simultaneously, it also comprises yoke plate, described yoke plate is provided with chute, described yoke plate is connected with cam with side arm respectively by chute, and described cam drives the side arm swing by yoke plate, thereby clamps or unclamp workpiece.
Described chute comprises shaped form chute and linear pattern chute, and described side arm is connected with yoke plate by the shaped form chute, and described cam is connected with yoke plate by the linear pattern chute, perhaps,
Described side arm is connected with yoke plate by the linear pattern chute, and described cam is connected with yoke plate by the shaped form chute.
The beneficial effects of the utility model are: the backswing action of side arm is changed into after the yoke plate realization by spring, and the backswing action can not occur asynchrony phenomenon because of the size of resistance, has equally avoided the fatigue fracture phenomenon yet.
